The Filter node implements various common image enhancement filters.
Controls the amount of influence the node exerts on the output image.
Standard image input.
The Soften, Laplace, Sobel, Prewitt and Kirsch all perform edge detection (in slightly different ways) based on vector calculus and set theory equations.
Slightly blurs the image.
Increases the contrast, especially at edges.
Softens around edges.
Creates a negative image that highlights edges.
Tries to do Sobel one better.
Giving a better blending than Sobel or Prewitt, when approaching an edge.
Performs a relief, emboss effect, darkening outside edges.
Standard image output.
